A compact design for ultra-sonic piezoelectric motor with embedded strain wave reducer for high torque applications

Abstract : Piezo-electric motors are interesting candidates and a good alternative solution to electromagnetic actuation. A limited number of mechanical components is required which leads to simple and compact designs. A high resolution and repeatability can be reached. They do not generate noise nor magnetic fields which make them easy to integrate in different environments. Nevertheless, some limitations remain such as the difficulty to create a piezo-electric motor with high torque capabilities.
